Semiconductor quantum dots [1]}, particularly in silicon [2]}, are attractive hosts for spin qubits in large-scale quantum computation applications, because of their assumed compatibility with conventional CMOS integration processes.
In addition, the \(\sim 100\)  nm spatial dimensions intrinsic to semiconductor spin qubits provide the potential to pack many millions of qubits inside a single quantum processor chip.
The last several years have seen significant progress in spin-qubit research that resulted in the demonstration of long coherence times [3]}, high-fidelity single- [3]}, [5]}, [6]} and two-qubit gates [7]}, [8]}, quantum algorithms [9]}, quantum non-demolition measurements [10]}, [11]}, and electron spin [12]} and charge [13]}, [14]} transfer.
